What Sebastian Sejer & Co A/S does
Sebastian Sejer & Co A/S is a Copenhagen-based privately held design agency founded in 2001, operating with a small core team (1-10 employees) under a network-based model that flexes in specialist talent per project. The firm delivers a full suite of design services spanning visual identity, graphic design, brand strategy, and digital solutions for Danish and international clients across enterprise, mid-market, startup, government, and nonprofit segments. Notable engagements include work for CBRE, Matas, Anora, Dagbladet Børsen, Empire Bio, A4 arkitekter og ingeniører, and VisitNordsjælland, with several client relationships extending across multiple years.
The agency's technical capability centers on headless CMS-backed web development, cross-platform publishing systems, and ERP integration (including a Microsoft Dynamics NAV integration for a Change of Scandinavia webshop). It has also built template and catalogue design systems that draw on client ERP data. The firm briefly operated two product ventures - the SmartSlap quiz app (2015-2018) and the Respace commercial property portal (acquired by Butikskompagniet in 2020) - both of which were ultimately divested or discontinued.
Revenue is generated exclusively through professional design services on a quote-based, project and multi-year contract model. Go-to-market is sales-led and relationship-driven, with no formal marketing function; client acquisition is dominated by personal recommendations and long-tenured referrals. There is no public pricing, no disclosed revenue, and no external investment, leaving the firm as a founder-led, self-sustaining boutique operation whose growth ceiling is principally constrained by the founder's available delivery capacity.
